TO ALL WHOM IT MAY CONGERN:

Be it known that I, HENDERSON ROSS, of Pittsburg, in the county ofAllegheny, in the State of Pennsylvania, have invented a new and usefulImprovement in Furnaces; and I do hereby declare thatthe following is afull and exact description thereof, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon.

The nature of my invention consistsin providing a furnace with a.detached metallic with a water-chamber. vMyinvention also consists inproviding the furnace with a metallic neck or throat, and stack orchimney, said neck and stack being furnished with water-chambers, theWholebeing constructed, arranged, and operating, substantially in themanner and forl the purpose hereinafter described..

To enable others skilled in the ar't to makeand use my invention, I willproceed to describe its construction and operation. 1n theaccompanyingjdrawings, which form part of my specifications- Y Figure 1is a. longitudinal section of my improvement in neck and stack of anordinary puddling-furnace.

Figure 2 represents a transverse section of the stack when cut throughat line x of iig. l.

Figure 3 represents a transverse section-of the neck of the furnace whencut through at line x of iig. 1.

In theV drawings, A represents the detached metallic clamp, which isprovided with a water-chamber marked in. B represents the lower part ofthe stack or chimney, furnished with a water-cl1amber, n, D, the widthof the door being equal to the breadth of the neck of the furnace. Crepresent the sides of the neck, which are provided with water-chambers,o, which are connected with the water-chambers n of the stack.

The water-chambers of the clamp, neck, and stack must beprovided withsuitable pipes for supplying them with water, and also pipes forcarrying olf the heated or waste water. The arrangement of these supplyand wastepipcs, andthe means for cleaning out the water-chambers I leavetethe skill andjudgment of the mechanic.

The dotted lines in iig. 1 are used for the purpose of showing therelationof-my improvement to the balance of` the furnace. 1 represent.`the crown of the furnace, 2v represents the bridge-wall, 3 representsthe grate-bars,

4 represents the bottom plate, 5 represents the bosh, and 5 representsthe form of the bottom of the neck, all

of which are constructed in the usual manner and with the ordinarymaterial. The back end, and that portion of the crown of the furnacedirectly over the fire-chamber z2, I propose making of iron, andfurnishing it with y a water-chamber, as indicated by the dotted linesmarked x3, which device Ipropose making the subject of anotherapplication for Letters Patent, and therefore will not at presentfurther describe it. The upper part of l the stack of the furnace-may beconstructed of brick or iron, with the bottom course of fire-bricklining resting on the offset marked c, shown in fig. 1, or the whplcstack may be constructed with the chamber 1t extending from the bettelnto the top of it. The door D is provided with a flange, z', forsupporting and holding brick lining. This door is used for the purposeof alfording a ready opening for cleaning out the neck or throat of thefurnace. The ferm, size, and the manner ofco-nstructing the` severalparts of my improvement, I leave to the judgment of the mechanic. 1twillreadily be observed that the sides C and clamp A may be soconstructed as to form onepart, with a single water-chamber, therefore Ido not confine my invention to making the. ncekor throat of the furnacein several parts.

The operation of my improvement is as follows: Water is conveyed intethe different chambers at the lowest point, and carried off at thehighest point. By thus supplying and carrying olf the water, thechambers will always be kopt full of cool water. The stack B, with itschamber 1t, may be used for generating steam, which may be utilized forany desired purpose.

The advantages of my improvement consist in saving brick, time, and costof repairing the neck of the furnace. `vThe `action of the furnace whenprovided with my improvement will alwaysbe uniform, which is a verygreat desidcrutum, and especially so in furnaces used for themanufacture of iron and steel. i

Having thus described the'nature, construction, operation, vclaim as ofmy invention, is-

clamp furnished and a door,

and advantages of my improvement, what Iv 1. A water-clamp for furnaces,constructed, arranged, and operatingisnb stantially as herein describedand for the purpose set forth.

2. Surrounding the neck or throat with water, substantially as hereindescribed and for the purpose set forth` HENDERSON ROSS.
